6989 Mega Core Magnetizer is a SpaceM-Tronset released in 1990. It comes with the M-Tron's main vehicle, which serves as a home-base (so to speak), as they never had any actual bases.
Providing housing for three minifigures, the Mega Core Magnetizer also was used for repair, storage, transporting, and a landing place for various craft.
The Mega Core Magnetizer supported three minifigures, two small ground vehicles, one flying vehicle, one storage pod, one repair pod, and one small container to hold the trans-neon green 1x1 rounds.

The Mega Core Magnetizer was the largest land vehicle from Space until Mars Mission was released. It is larger than many starships, yet contains a small number of minifigures. The overall colour scheme of the set is black and red, with some transparent green. A unique feature of the large vehicle is its cockpit, which is covered by a huge transparent neon green part normally used in buildings as part of the walls.

Stored inside the Mega Core Magnetizer are a pair of land vehicles. They attach with magnets to the Magnetizer, or carry magnetic boxes to the large vehicle. They have two small lights on them, and a control panel. Each one is black and red, and can be piloted by one astronaut. In addition to these two vehicles is a slightly larger speeder. It too has a magnet to attach to other vehicles or to carry magnetic boxes. It has a seat-back and a control panel, along with two rear thrusters.

The Mega Core Magnetizer is made up of two sections connected by a hinge. The first section is the control, and the second section carries other vehicles and containers. At the back of the second section is a bay door which can be lowered into a ramp, allowing vehicles to drive it and boxes to be carried up. On either side of the walls on the back are two large rocket thrusters which can swivel around to point behind the vehicle. There are holes into which an object can be placed and it will slide down a ramp into the storage bay. On top of this section is a crane. The end of the crane is a magnet, allowing it to drop objects into the storage bay. The crane can extend and contract, and also can swivel around. It has a light and four back lasers. On it is a satellite dish and a radar antenna.

The Mega Core Magnetizer

The cockpit has three seats, one for each of the three minifigures included in this set. Like many other older Space sets, it is short in Minifigures. There are also a pair of walkie-talkies in the cockpit. Behind it are two large Grille plates. On them is a disk with the M-Tron logo which can be angled up and down. A large magnetic container is placed on each of these. They have a rectangular shape, with a magnet on top. They each carry two jetpacks, each having one fire hose.

The Mega Core Magnetizer is no different from many other of Space's largest vehicles in that it comes with three minifigures. They are all identical. They have black helmets with transparent green visors. Their torsos are patterned with the M-Tron Logo. Their arms are white, as are their legs.
